PAUL SI-IWAIB, on NEW YORK, N. Y.

WATER-CLOSET SEAT.

I To all whom it may concern:

Be it known that I, PAUL SHWAB, a citizen of the United States, andresident of borough of Manhattan, in the city and county of New York andState of New York, have invented certain new and useful Improvements inIVater-Closet Seats, of which the following is a specification.

In the construction of a wooden seat for use, on the ordinary type ofporcelain water closet bowl, it is found necessary to guard against manyconditions, any one of which might render the seat temporarily orpermanently useless. One of these is the unequal expansion due to thecombined action of the atmospheric conditions above and the dampnessfrom the water that is constantly in the bowl below. Another may be thestrain due to a sudden dropping of the seat against the porcelain bowl,which is apt to break or crack the seat particularly at the junction ofthe separate pieces that go to make up the whole. A third may be thestrain from an uneven mounting of the seat, or to the unequal surface ofthe bowl, which it may be required to rest upon.

Many attempts have been made by myself and others to construct a seatwhich would successfully resist the strain and stress from any abnormalcondition, whether it be one of those which I have enumerated or anyother which may accidentally present itself.

In this invention I have endeavored by a certain combination of a tongueand groove with a certain novel means of inserting a longitudinal dowelsecured in place by transverse pins to obtain the desired result in acheap though highly eflicient manner. Extended experiments have provedthat the several dowels do more than simply hold the adjacent partstogether. They strongly oppose any twist or warp which would in anyother construction exhibit itself. Metal seats have been used butbecause of the weight and their natural coldness are undesirable. Thisis true of wooden seats which have a great deal of metal in their jointsand fastenings.

The following is what I consider the best means of carrying out thisinvention.

The accompanying drawings form a part of this specification.

Figure l is a plan view. Fig. 2 is a section on the line 2-2 in Fig. 1.Fig. 3 is on a larger scale, in plan, and shows the holes and groovesindicated by dotted lines.

Specification of Letters Patent.

Application filed May 11, 1909.

A forms the right side of Patented July 12, 1910. Serial No. 495,325.

In this figure the structure is disjointed.

Fig. 4 shows a dowel and the retaining pins. Similar letters ofreference indicate like parts in all the figures where they appear.

A seat of any of the long approved desirable shapes and sizes isindicated at A.

It is made of wood and is in four main parts. Considering the figures,the part indicated by A is at the top which, when the seat is in use isthe front portion. A is the section at the right. A the bottom, and Athe section at the left.

The part A in Fig. 3 carries at its lower right hand end, a tongue orrabbet B and is provided with an inwardly extending hole a drilledcentrally in the end, and a transverse hole a On the other end, the leftend in the figure, a deep groove 5 is produced and also a centrallylocated hole a corresponding in depth and diameter to the hole a. Atransverse hole a corresponding in depth and diameter to the hole a isproduced in the same manner as the hole a by drilling from the outsideedge or rim of the seat inward into the hole a and beyond it, nearlythrough the whole width of the side of the seat. The next section, thepart the seat and is provided upon its uppermost end with a deep groove72 sufliciently deep and broad to receive the adjacent tongue B of thepart A A large hole a of approximately the same diameter as the hole ais produced, extending downward from the front end, and a transversehole a corresponding in depth and diameter to the hole a is drilledinward from the outside edge, the right edge in the figures, passingthrough the hole a and ending close to the left, the inner edge of thispart of the seat. The lower end of the part A carries a protrudingtongue 13 corresponding in' all respects to the tongue B on the part A Alarge hole a and a small hole a are produced to correspond to the otherholes of similar size and location, which have been described. The thirdsection of the seat is the part A at the bottom, and in use this formsthe back section of the seat and is the heaviest and largest of the fourmain parts. The upper right end, the end adjacent the part A is providedwith a groove of sufficient dimensions and depth to receive the tongue Bof the part A This groove is indicated at 6 Holes a and a similar in allrespects to the corresponding holes already described are produced inthis upper right hand end of the part A The left end also extends upwardas this section describes an are like the part A though on alargerscale. This left end is provided with an upwardly extendin tongue B andcentrally located in this enc is a downward extending hole a and atransverse hole a. The fourth and last of the principal members of myseat is the part A forming the left side connecting the downwardlyextending left end of the part A and the upwardly extending left end ofthe part A together, thus completing the series. The lower end of thepart A is provided with a deep broad groove 6 and an upwardly extendinghole a centrally located. I have also produced a transverse hole a onthis end. The upper end of the part A carries an upwardly extendingtongue B and is provided with a large downwardly extending hole at and atransverse hole a.

At Fig. 4 I have shown a dowel C which in my device is around wooden pinof the required length and of such a diameter as to allow it to fitsnugly into the large vertically extending holes which have beenprovided for it in the ends of the four main parts of my seat. In thedowels C I have produced two small holes 0 and I provide smaller dowelsor pins D to match closely into these holes.

Having fully described the independent sections of my device I will nowdetail the method of uniting the whole as certain elements may appearwhich have not been fully described in the specification. I first selectfour pieces of wood of much the same length, breadth and thickness and Imiter each end of each piece, in such a manner so that when the fourpieces are placed together with their miter joints adjacent a squarefigure will be formed. Before placing them together a tongue and grooveis formed, the tongue on one end of each block and a properly shapedgroove on the other end. At about the center of each tongue and groove ahole of sutlicient depth and diameter to accommodate the large dowel Cis drilled and now the parts are ready to be assembled. Care must betaken in accomplishing this to glue well the dowels, tongues andgrooves. Dowels are entered a small distance in the holes a, a a, and aand the four main sections are approached closely together. The properdowels are then entered into the holes a, a a and a. The four parts arenext pressed evenly and firmly inward and the tongues 13, B, 13 and Bare glued into their re spective grooves. After the joints are closed astight as possible the holes a a, a, a, a, a, a and a are drilled and apin D is glued and inserted into each of these small holes. The littleadditional strain upon the larger dowels just before they become tightis found not to be objectionable. After the glue is well set and theparts are securely held together a pattern of the desired shape issketched upon the broad fiat face of the wooden form and then with aband or jigsaw the surplus wood is skilfully removed, and the seatassumes the proper shape. Holes are next produced for the accommodationof the small transverse pins, near each junction of two of the mainparts, one on each side of said junction. Into these holes the smallpins are inserted after they have been well glued.

The finishing of my seat is carried on in the usual way with thisgeneral class of apparatus, by sand papering, varnishing, etc., and theseat is complete. If the work has been well and skilfully done theresult will be a strong locked jointed seat well adapted to resist allof the strains of whatever wear and tear it may be subjected, and onethat will be found almost impossible to pull apart. Care should be takento have the grain of the wood in all of the parts run lengthwise thepart, thus avoiding cracking because of a short grain.

I attach importance to the arrangement of the dowels and retaining pins.The dowels because they run through the center, a thick part of the seatand can therefore be made thick and long without fear of breakingthrough. To the pins, because they run acrossthe greatest width of eachsection and can therefore be made of great length and yet find a firmsupport on both sides for their entire length.

Modifications may be made within the scope of the appended claimswithout departing from the principle or sacrificing the advantages ofthis invention.

I have described the use of glue but this can well be dispensed with. Ihave described the grain of the wood as running in a direction to securethe best results, this can be ignored.

The number of parts which go to make up my seat can be varied within awide range yet the whole will operate successfully.

That I claim and desire to secure by Letters Patent is:

1. A water closet seat comprising four complementary curved sections,one end of each section being provided with three recesses, the centerrecess a a etc. being of the greatest depth, the other end of each saidsection, which is also provided with a deep recess carrying a pluralityof tongues of less thickness than the main body of the section, each endof each said section being provided with a hole a a 60' etc., extendinginwardly from the outer edge thereof.
